Embodiment Construction

[0014] Below in conjunction with the embodiment shown in the accompanying drawings, further illustrate the content and working principle of the present invention.

[0015] As shown in Figure 1. This type of furnace adopts a two-in-one structure, and the upper part of the body is provided with a hopper 1 for storing biomass briquettes. The fuel enters the gasification combustion chamber 3 through the hopper 1 . The gasification combustion chamber 3 is cooled by the water interlayer 2 to absorb heat. A water-cooled fire grate 4 is provided at the bottom of the gasification combustion chamber 3 . There is a thicker fuel layer inside the gasification combustion chamber 3 . The fuel undergoes drying, pyrolysis, gasification and reduction reaction, and the pyrolysis gasification gas and reduction gasification gas of the fuel pass through the water-cooled grate 4 downwards at high temperature and burn in the layer combustion combustion chamber 6 . The unburned carbon in the gasif...

Abstract

The invention relates to a burning gasifying boiler which uses biological fuel, for resolving the problems as instable burning, over air and pollution or the like. The invention has novel structure, less steel consumption, small volume, and high thermal efficiency. The invention comprises a material storage room, a gasifying burning room, a multilayer burning room, a slag room, and a heat exchanger. The invention is characterized in that: the burning room comprises integrated gasifying burning room (3) and multilayer burning room (6) while they are separated by the water cooling furnace bed (4); the grid (7) is arranged at the bottom of multilayer burning room (6); the side of the multilayer burning room (6) via the smoke window (10) is communicated with the slag room (12) in the chamber of boiler; and the smoke tube heat exchange face (13) in the chamber is mounted between the smoke box (15) at the top of boiler and the slag room (12).

Description

technical field [0001] The invention relates to a clean combustion gasification boiler using biomass molding fuel. Background technique [0002] At present, energy and environmental issues have become the focus of global attention. Although oil, coal and natural gas are still the main sources of fuel, with the depletion of fossil energy and the increasingly serious environmental problems, the development and utilization of clean and renewable energy has become an important issue. pressing issues. In this context, biomass energy is the only renewable energy that can be stored and transported, and its efficient conversion and clean utilization are increasingly valued by the world. [0003] Biomass energy is a natural resource that uses green plants to store solar energy in plants through photosynthesis, and is a cheap way to store solar energy. The emission of biomass energy will not exceed the amount of carbon absorbed during its growth, and zero emission of carbon dioxide ...
